Which two items are the two common methods of programming CNC machines?

• A. Conversational programming and CAM
• B. G-code and CAM
• C. Conversational programming and G-code
• D. CAM and Manual programming

Answer: (A)

Programming CNC machines is commonly done through two pathways: conversational programming and CAM. Conversational programming provides a quick, dialog-based way to define operations directly on the machine control, which is handy for simple parts and fast setups. CAM software, on the other hand, takes a CAD model, generates toolpaths, and outputs machine-ready code, making it ideal for complex geometries and repeatable production. Together, these two approaches cover fast, on-machine entry for straightforward jobs and off-machine, software-driven generation of detailed, optimized programs.

G-code is the language the machine understands, so it’s what you end up with after either method, rather than a distinct programming approach itself. Manual programming exists but is less common today compared to these two.
